SPECIFICATION forming part of Letters Patent No. 429,372, dated June 3, 1890.

Application filed March 6, 1890. Serial No. 342,935. (No model.)

To all whom it may concern.-

Be it known that I, FRANK BALDERSON, of Oketo, in the county of Marshall and State of Kansas, have invented a new and Improved Belt-Replacer, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved belt-replaeer which is simple and durable in construction and very effective in operation, requiringbut little labor to place the belt on the pulley or wheel.

The invention consists of a segment adapted tobe clamped to the rim of the pulley and to project in line therefrom and a curved arm pivoted to one end of the said segment.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying .drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all of the figures.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is a similar view of the same in a different position; and Fig. 3 is a face view of the same as applied, the wheel being in section.

The improved belt-replacer A is provided witha segmentB, having the same radius as the wheel or pulley on which it is to be applied. From the segment B extend transversely arms 0, adapted to pass onto the outside of the rim of the pulley or wheel on which the belt-replacer is to be applied, and from the said segment projects a plate or arm D, extending between the arms 0 and adapted to engage the inside of the rim of the wheel or pulley F on which the replacer is to be used. A set-screw E screws in this plate D to fasten the latter and the segment B onto the rim of the pulley, the segment extending in line with the rim. One end of the segment B is provided on the outside edge with an upwardly-bent flange B, which serves to shift the belt onto the rim of the pulley or wheel, as hereinafter more fully described.

On the opposite end of the segment 13 is formed a hinge G, connected with a curved arm H, adapted to swing into the position shown in Fig. 1 to permit of starting the belt I, and the said arm is preferably curved in the shape of a segment corresponding to the segment Bthat is, to the rim of the pulley F. One end H of the said arm H is curved inward, as plainly shown in Fig. 1, so that the belt, when engaging the said arm H, is not scratched.

The operation is as follows: WVhen the belt I is to be placed on the rim of the pulley F, the opera-tor first clamps the segment B to part of the rim of the said pulley by passing the arm 0 onto the outside of the rim and the plate D on the inside of the rim and then screwing up the set-screw E.

One edge of the segment B then abuts against one edge of the rim of the pulley F. The pulley is then turned into the position shown in Fig. 1, the arm H is turned so as to stand at an angle to the segment B, and then the operator places the belt I over the said curved arm H, as illustrated in Fig.1. The operator then turns the pulleyF in the direction of the arrow a, so that the weight of the belt I causes the outer end of the arm H to swing downward onto the segment B, so that the said arm H extends in line with the rim of the pulley F. The belt finally passes onto the uncovered part of the segment 13 to finally engage the flange B',which then stands at the top of the pulley F and acts to throw the belt onto the rim of the pulley F. As soon as the belt has touched the rim it readily slides over the entire rim when a complete revolution has been given to the pulley F. The operator then loosens the set-screw E and removes the belt-replacer from the pulley by sliding the said replacer to one side.

It will thus be seen that the belt-replac'er is very simple in construction, can be readily fastened to the drive-wheel or pulley, and it requires but little labor to place the belt on the rim of the pulley.

tially overlapping it and adapted to be swung at an angle to the segment and pulley to receive the belt, return to its normal position, and direct the belt upon the pulley, substantially as set forth.

2. In a belt-replacer, the combination, with a segment provided with arms and plate adapted to engage the inside and outside of the rim of the pulley or wheels and a setscrew for fastening the said plate to the rim of the pulley, of a curved arm pivoted on the said segment, substantially as shown and described.

3. In abelt-replacer, the combination, with a segment, of a curved arm. pivotally connested at or near its middle with the segmentarms projecting from the said segment and adapted to engage the outside of the pulley, a plate held on the said segment and adapted to engage the inside of the said pulley, and a set-screw screwingin the said plate to clamp the segment to the pulley, substantially as shown and described.

4. In a belt-replacer, the combination, with a segment, of a curved arm pivotally connected at or near its middle with the segment and a turned-up flange formed at one corner of the said segment opposite the piv-
